Here we installed the virtualization package group (notice the prefix): it includes everything needed for virtualization on Fedora, except for the qemu-system-arm package, that we installed separately.
QEMU SYSTEM ARM INSTALL
To install them on Fedora, we can use the dnf package manager: $ sudo dnf install qemu-system-arm Qemu and kvm are available in the software repositories of the main Linux distributions. To be able to virtualize our Raspberry Pi Os we need to install it on our favorite distribution, together with the qemu-system-arm package, which provides the system emulator for ARM systems. On Linux it is often used in combination with kvm, which is a full virtualization solution included in the kernel.
We can use it to run operating system for any type of machine. Qemu, as defined on the official website is a “generic and open source machine emulator and virtualizer”. $ – requires given linux-commands to be executed as a regular non-privileged user # – requires given linux-commands to be executed with root privileges either directly as a root user or by use of sudo command Requirements, Conventions or Software Version Used NOTE: Choose a pair of address on a different sub-net to any real network the PC is attached to otherwise the IP routing is going to get mixed up.How to run the Raspberry Pi Os in a virtual machine with Qemu and Kvm Software requirements and conventions used Software Requirements and Linux Command Line Conventions Category The technique used here is to create a TUN/TAP network device and connect it to the qemu process, with the host PC tap interface being 192.168.1.1 and the target address being 192.168.1.101. You need to configure a network interface so that you can communicate with the emulated target just as if it was a real board. Edit /etc/inittab and change the reference to ttyS1 to ttyAMA0.
QEMU SYSTEM ARM SERIAL
You will have to make one small change because the Digi CCW9 target board we use for training has the serial console device as ttyS1 whereas on the Versatile it is ttyAMA0. Download it, if you don't have it already, create a directory such as ~/rootdir and extract it there.
Or, you can download a pre-built copy of zImage. I have tested these instructions with qemu version 0.12.3 which comes with Ubuntu 10.04, so begin with I have chosen to use the Versatile board with an ARM926E core. For arm, we have the ARM Integrator, RealView and Versatile development boards, the Nokia N800/810 and various others. For each processor type, there are emulations of a number of hardware platforms. Each one is a separate executable: qemu-system-arm and qemu-system-mips for example. Qemu can emulate a wide range of processor types, including arm, cris, m68k, microblaze, mips, ppc and sh4.
The objective, then, is to use qemu to create an arm926 environment that can run a typical embedded distribution (we use the Ångström distribution ), using an NFS root mount to a file system on the host PC. Thinking about it a bit more, I realise that the situation is general and common enough to be useful to many people (or so I hope) and so I have written this tutorial. I said, you could use qemu to emulate an ARM target that is rather similar to the one we actually use.
QEMU SYSTEM ARM HOW TO
At the end of one of my training courses recently we got into a discussion about how to continue working with the code and configurations developed during the course after everybody had gone home and they no longer had a target board.
